No. AFAIK, none of the P4s support VT. The newer Pentium D chips have
VT support.

When I did the testing, it was with on a single Pentium 4 with
hyperthreading turned off. So it should have been a good base test.
Plus, the test I did wasn't quite up to standards, it was only so I
could make conclusions for my own use. If I get a chance, I'll do the
test with multiple CPUs.
I've heard that using an SMP kernel is actually faster even if you
only have 1 CPU. Kinda strange.

Yeah, that would be interesting. I only really have my workstation at
home to do that test with though.
